“…Natural factors which have control over water chemistry include precipitation pattern and amount, geological features of watershed and aquifer, meteorological factors, and various rock-water interaction processes in the aquifer (Arnade, 1999;Singh, Raju, & Ramakrishna, 2015). Human activities which influence the water chemistry include dumping of solid waste, domestic and industrial waste, and mining and agricultural activities (Hem, 1991;Raju, 2007;Singh, Raju, Gossel, & Wycisk, 2016;Todd, 1980).

This study is aimed to assess the groundwater excellence within the rural areas of Sant Ravidas Nagar (Bhadohi), Uttar Pradesh, India. In the current work, estimation of groundwater excellence indices has been done to recognize the water quality for the appropriateness of groundwater resource for drinking and agricultural use. Twenty groundwater samples were collected and investigated for diverse geochemical parameters viz, pH, total dissolved solids (TDS), total hardness, cations and anions. The groundwater of the study region is neutral to slightly alkaline in nature. Piper's diagram classification shows that majority of the samples belong to CaMgHCO 3 hydrochemical facies. Gibbs plot specifies that majority of samples falls in rock dominance. The water quality index shows that the entire sample is under excellent water category. On the basis of TDS, all the samples are within the range of desirable to permissible for drinking and agriculture purpose. Forty percent samples of the study region are having nitrate content more than permissible limit (>50 mg/l) which is not fine for individual use. Poor drainage, domestic waste and use of N fertilization on farming land may be the main sources of nitrate in groundwater of the study region. On the basis of different water quality indices, groundwater of the study region is fit for agricultural use.

“…There are diverse reports in literature which assess the geochemical characteristics of surface water systems, as well as anthropogenic contamination influenced by factors such as agricultural fertilizers, sewage effluents, evapotranspiration, water-rock interactions and ionexchange in several parts of the world (Abdesselam et al 2013;Alaya et al 2014;Iranmanesh et al 2014;Kim et al 2015;Khashogji and El Maghraby 2013;Nandimandalam 2012;Singh et al 2016). However, in Ghana, there are few such reports (Boateng et al 2016;Helstrup et al 2007;Fianko et al 2010;Yidana et al 2012).…”

Background: Geogenic and anthropogenic activities such as Artisanal and illegal gold mining continue to have negative impacts on the environment and river basins in China. This work studied the hydrogeochemical characteristics of surface water from the Birim River basin and assess the quality of water for human consumption and agricultural activities. In addition, the ecological risk assessment for Cd, Zn, Pb and As in sediment was evaluated using pollution indices. Results:The results show that the turbidity, temperature, colour and iron concentration in the water samples were above the World Health Organization guidelines. Multivariate analysis explained five components that accounted for 98.15% of the overall hydrogeochemistry and affected by anthropogenic and geogenic impacts. The surface water was observed to range from neutral to mildly acidic, with the dominance of HCO 3, and Na + in ionic strength. The Piper diagram reveals five major surface water types: Na-HCO 3 -Cl, Na-Cl-HCO 3 , Na-Ca-Mg-HCO 3 , Na-Ca-Mg-HCO 3 and Ca-Na-Mg-HCO 3 . The Gibbs plot showed that the major ion chemistry of surface water was mostly influenced by atmospheric precipitation and the water quality index showed that the majority of the surface water from settlements within the Birim River basin were of poor quality for drinking and other domestic purposes. However, irrigation suitability calculations with reference to sodium adsorption ratio, residual sodium carbonate, and magnesium ratio values, together with Wilcox and USSL models indicated that the surface water within the area under study was suitable for agriculture. The potential ecological risk for single heavy metals pollution and potential toxicity response indices gave low to considerable ecological risks for the sediments, with greater contributions from Cd, Pb and As. Whilst geo-accumulation indices indicated that the sediments ranged from unpolluted to moderately polluted Modified degree of pollution and Nemerow pollution index calculations which incorporate multi-element effects, however, indicated no pollution. Conclusion:There are some levels of both potential ecological risks and health hazards in the study area. Hence continuous monitoring should be undertaken by the relevant agencies and authorities so that various interventions could be put in place to prevent the situation from deteriorating further in order to protect the inhabitants of the settlements within the Birim River basin.

“…So, the hydrogeochemical processes of the groundwater vary spatially and temporally, depending on the geological and chemical characteristics of the aquifer. In various parts of the world, numerous studies have been carried out to assess the geochemical characteristics of groundwater affected by contamination from human activities such as sewage effluents, agricultural fertilizers and ion-exchange, evapotranspiration and water-rock interactions which result in an increase of the ion concentration making water unfit for drinking and agricultural purpose [5]- [12]. Determination of groundwater composition and its interpretation is very important for the evaluation of its suitability for domestic, irrigation and industrial uses.…”

Understanding of the aquifer hydraulic properties and hydrochemical characteristics of water is crucial for management plan and study skims in the target area, and flow motions and chemical species of groundwater are regarded as precious information on the geological history of the aquifers and the suitability of various usages. Cations and anions of groundwater are used to estimate the characteristics and origin of groundwater. In this study, we try to evaluate the quality of groundwater based on the comparison of the physiochemical characteristics and distribution of cations and anions in groundwater from rural areas. Therefore we focused on the evaluation of groundwater as some specific purposes such as agricultural and industrial use, general types of groundwater, lithological origin of chemical component in groundwater. In this point of view, major objectives of this study were grouped as following three categories: 1) quality assessment of groundwater as a special usage (agricultural, industrial); 2) determination of groundwater types; 3) tracing of ion sources of groundwater. The quality of agricultural water was evaluated using SAR, sodium (%), RSC, PI, SSP, MH, PS, and Kelly's ratio, and was classified as SAR (Excellent (100%)), Sodium ((Excellent (34%), Good (55%), Permissible (9%), Doubtful (1.6%), Unsuitable (0.4%)), RSC (Good (95.7%), Medium (3.5%), Bad (0.8%)), PI((Excellent (40.6%), Good (59%), Unsuitable (0.4%)), SSP ((Excellent (26.3%), Good (59.8%), Fair (13.1%), Poor (0.8%)), MH ((Acceptable (94.4%), Non-Acceptable (5.6%)), Kelly's Ratio ((Permissible (93%), NonPermissible (7%)), PS ((Excellent to Good (98%), Good to Injurious (1.2%), and Injurious to Unsatisfactory (0.2%)). Evaluation based on the Wilcox diagram was classified as "excellent to good" or "good to permissible", and the water quality evaluated using the U.S. salinity Laboratory's Diagram was classified as C1S1 (Excellent/Excellent) and C2S1 (Good/Excellent). And, in the applications of two factors of Langelier Saturation Index (LSI) and Corrosive ratio (CR), we could get similar results for defining the suitabilities of groundwater for the industrial purpose. And the groundwater samples were also clas- Ca -HCO + − type. And, estimation of dominance type (evaporation, rock, precipitation) based on the Gibbs diagram showed that the origin of anion and cation in groundwater are from the rock-do-minance, and the estimation of origin of anions using the Chadha diagram showed that the most of the ionic species was originated from the interactions between alkaline earths and alkali metals contained in the soil. And through the source-rock deduction followed by the comparison of Gibbs and Chadah diagram, it was shown that the chemical components in the groundwater were mostly induced from the water-rock deduction and major types of groundwater samples following the Chadah diagram were categorized such as following group types: dolomite type, gypsum type, alkaline and alkaline earth type.
